I got garbled exception message as following when I run `livenmethods` CLHSDB command:
sun.jvm.hotspot.debugger.DebuggerException : ?w???????W My Windows laptop is set Japanese Locale, garbled message was written in Japanese. saproc.dll would throw exception via [ThrowNew()](https://docs.oracle.com/en/java/javase/15/docs/specs/jni/functions.html#thrownew) JNI function, but it accepts UTF-8 encoded message. However [FormatMessage()](https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-formatmessage) Windows API might not return UTF-8 encoded string on Japanese locale. java.dll (libjava,so) provides good functions to resolve this issue. We can convert localized (non ascii) chars to UTF-8 string. I use them in this PR and remove `FormatMessage()` call from sadis.c. And also I remove `-D_MBCS` from compiler option because [MBCS has been already deprecated](https://docs.microsoft.com/ja-jp/cpp/text/support-for-multibyte-character-sets-mbcss) - it does not seem to add to any other executables. ------------- Commit messages: - 8259045: Exception message from saproc.dll is garbled on Windows with Japanese locale Changes: https://git.openjdk.java.net/jdk/pull/1928/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1928&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8259045 Stats: 50 lines in 2 files changed: 4 ins; 37 del; 9 mod Patch: https://git.openjdk.java.net/jdk/pull/1928.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1928/head:pull/1928 PR: https://git.openjdk.java.net/jdk/pull/1928
